CPA Business Valuation: When You Need One and What to Expect

CPAs are often the right choice for business valuations because of the tax-and-financial integration they bring. Most ABV-credentialed CPAs (Accredited in Business Valuation, AICPA designation) work at CPA firms, can integrate the valuation with broader tax planning, and have credibility with the IRS for tax-related valuations. The trade-off: CPA-driven valuations are sometimes less specialized than valuations from independent appraisers focused exclusively on valuation work.

This guide covers when a CPA business valuation is the right choice, what credentials to look for (ABV vs. CVA vs. ASA), typical fees, and how CPA-driven valuations compare to alternatives. We’re CT Acquisitions, a buy-side M&A advisory firm.

When a CPA business valuation is the right choice

Tax-related valuations

For gift tax, estate tax, charitable contribution, and ESOP valuations, CPAs are often the strongest choice because:

• IRS credibility (CPAs have Federal credentialing the IRS recognizes)
• Tax integration (the same firm can handle the related tax filings)
• Defensible methodology (ABV credential requires USPAP-compliant work)

Litigation support

For partnership disputes, shareholder disputes, and divorce-related valuations, CPAs with litigation support experience often work alongside attorneys to provide both expert testimony and report preparation.

Pre-transaction planning

Sellers planning to sell within 1-3 years often hire CPAs for tax planning that includes valuation: structuring entities (S-corp vs. C-corp for QSBS), basis planning, gift / installment sale planning. The valuation is part of broader tax strategy.

CPA credentials for valuation

ABV (Accredited in Business Valuation)

AICPA’s designation for CPAs specializing in business valuation. Requires CPA license plus business valuation training, experience, and exam. Most ABVs work at CPA firms. Strongest credential for CPAs doing valuation work.

CVA / AVA (NACVA Credentials)

NACVA credentials available to CPAs and non-CPAs. Many CPAs hold both CPA and CVA. Less rigorous than ABV in some respects, but widely recognized.

Other credentials

Some CPAs offer valuation services without a specific valuation credential. Be cautious here, valuation is a specialty practice and CPAs without specific credentials may not produce defensible work.

Typical CPA valuation fees

How to choose between a CPA, an independent appraiser, or a free tool

Choose a CPA when

• The valuation is for tax purposes (gift, estate, ESOP, charitable)
• You want integration with broader tax/financial planning
• Your existing CPA has ABV credential and relevant experience
• Cost is a consideration (CPAs sometimes price below independent appraisers)

Choose an independent appraiser (ASA-credentialed) when

• The valuation is for high-stakes litigation
• The business is highly complex or has specialty industry issues
• You need the most defensible report possible
• Cost is less important than report rigor

Use the free tool when

• You’re researching what your business might sell for
• You’re preparing for broker conversations
• You’re sanity-checking a quoted valuation
• You don’t need a defensible third-party report

The five pillars of how CT Acquisitions works

What’s actually in a CPA business valuation report

An ABV-credentialed CPA’s valuation report follows AICPA SSVS (Statement on Standards for Valuation Services) standards. The structure isn’t arbitrary, it exists so the valuation holds up if challenged in litigation, IRS examination, or partnership dispute. The major sections:

Executive summary

2-4 pages summarizing the conclusion: business name, valuation date, scope of work, methodology, and the conclusion as a range or point estimate. A quality summary states what is being valued, as of what date, for what purpose, using what methodology.

Business description

4-8 pages describing the business: ownership history, services/products, customer base, employee count, geographic markets, competitive position, key risk factors. Specific customer concentration data and key-person dependency identification matter here.

Financial analysis

8-15 pages: 3-5 years of historical financials common-sized to revenue, with year-over-year trend analysis and comparison to industry benchmarks. Identifies the “run-rate” year used for valuation.

Normalized earnings (the most important section)

Where EBITDA add-backs and adjustments happen: owner’s above-market salary, personal expenses run through the business, one-time/non-recurring items, owner’s perks, depreciation methodology normalization. Every add-back should have a brief explanation and documentary support reference.

Valuation approaches

The CPA considers three approaches: income approach (DCF or capitalization of earnings), market approach (comparable transaction multiples and guideline public companies), and asset approach (sum of assets minus liabilities, rarely the primary method for operating businesses). The report reconciles these into a single conclusion.

Conclusion and appendices

The reconciled value (usually a range), the reconciliation rationale, detailed financial statements, normalization schedules, comparable transaction details, source citations, and the appraiser’s qualifications. The appendices are where audit defense lives.

Section 1042 ESOP deferral explained (the big CPA-valuation use case)

One of the most powerful tax tools in business succession is the Section 1042 deferral, available when selling stock to an ESOP. Here’s how it works: if you sell C-corp stock to an ESOP that owns at least 30% of the company after the sale, you can defer capital gains tax indefinitely by reinvesting the proceeds in “qualified replacement property” (essentially U.S. publicly-traded stocks and bonds). The deferral lasts until you sell the replacement property; if you hold it until death, the basis steps up and the gain may never be taxed.

This is why ESOP transactions almost always require a CPA-driven valuation: the IRS scrutinizes ESOP valuations closely (the ESOP can’t pay more than fair market value), and an ABV-credentialed CPA’s USPAP-compliant report is the standard. The combination of Section 1042 deferral plus the S-corp ESOP tax exemption (if the company elects S-corp status owned by the ESOP, the company pays no federal income tax) makes ESOPs one of the most tax-advantaged exit structures, though the setup cost ($100K-$500K) and ongoing fees ($25K-$75K/year) mean ESOPs make sense mainly for businesses with $5M+ EBITDA and 30+ employees.

Frequently asked questions

Should I hire a CPA for my business valuation?

For tax-related valuations (gift, estate, ESOP), yes, CPAs with ABV credential and tax integration are often the strongest choice. For litigation or complex business valuations, ASA-credentialed independent appraisers may be better. For research purposes, our free tool is sufficient.

What does an ABV-credentialed CPA cost?

$5K-$10K for sub-$2M businesses (calculation or limited-scope conclusion). $15K-$30K for $2M-$10M businesses (full conclusion of value). $30K-$75K for $10M-$50M. Litigation valuations cost more (1.5-2x standard) due to defensibility requirements.

What’s the difference between an ABV CPA and an independent appraiser?

ABV CPAs are CPAs first, valuators second, often with broader tax/financial integration. Independent appraisers (often ASA-credentialed) are specialists who do nothing but valuation work. ABVs are typically the right choice for tax purposes; ASAs for high-stakes litigation.

Can my regular CPA do my business valuation?

Only if they have specific valuation credential (ABV, CVA, or AVA) and experience. Generalist CPAs without valuation credential may not produce defensible work. Ask about credential and recent valuations done in your sector and size range.

How long does a CPA valuation take?

Calculation engagements: 2-4 weeks. Full conclusion of value: 4-8 weeks. Litigation valuations: 6-12 weeks.

Will the IRS accept a CPA valuation?

ABV-credentialed CPAs produce IRS-acceptable work for gift, estate, and other tax-related valuations. CPAs without specific valuation credentials may not. The credential and the methodology compliance (USPAP-compliant) matter more than the firm name.

Should I get a valuation from my own CPA or an independent one?

For most tax purposes, your own CPA (if ABV-credentialed) is fine and often more efficient. For litigation or contested matters, independent valuator is often better because it removes any appearance of bias. For ESOP valuations, regulations require independent valuator; your firm’s CPA can’t do it.

What’s the cheapest credible business valuation?

For research: our free tool. For paid: calculation engagement from ABV-credentialed CPA, $2K-$5K for sub-$2M businesses. Calculation engagements are limited-scope but adequate for many internal planning purposes. Conclusion of value reports are more rigorous but cost 2-3x more.
